2Adjusting R-Net settings
2.1 E-bx settings under the menu “Seating Amylior ISM”
Actuator number and its functionality
To access all actuators controlled by e-bx, use the following path: “Seating Amylior ISM Actuator Setup”. In this
submenu, the legend for each actuator number is as follows:
1 = Seat tilt actuator
4 = Center mount legrest actuator
2 = Backrest recline actuator
5 = Left legrest actuator or left stander actuator
3 = Seat elevate actuator
6 = Right legrest actuator or right stander actuator
The functions assigned to actuators 5 and 6 depend on the chair’s power options. If the chair has the standing
option, actuators 5 and 6 will be assigned to the standing module. If the chair has the separate power legrests, then
the actuators 5 and 6 will be assigned to the left and right legrests.

•Note 1 : Not applicable on actuators for very heavy-duty seat tilt (450 lb to 550 lb).
•Note 2 : If the chair has the power standing option, this setting should never be other than "0", otherwise
the standing function will not work.
•Note 3 : Setting the height limit can be determined with the following "rule of three": Height limit value
needed in % = (Height limit value in inches x 100)/11 inches (maximum height range).
E.g. Height limit value needed is 5.5 inches →(5.5 X100)/11 = 50%.
Therefore, the height limit value of Max limit #3 is 50%
•Note 4 : Not applicable on actuators for heavy-duty seat elevate (300 lb to 400 lb).
•Note 5 : If the chair has the power standing option, minimum setting of center mount legrest is 21°. It is
possible to change this value, but watch for leg hyperextention when in standing mode.
•Note 6 : Minimum and maximum limits for the left and right stander actuators must be set at the same
value.
•Note 7 : It is strongly recommended not to set this limit lower that -68° (example -70°) because the legrest
mechanism may collide with the base of the chair.
•Note 8 : This setting should never be other than "0" as this would prevent the seat tilt and seat elevate
from functionning.
•Note 9 : WARNING! If the chair has the power standing option, it is not recommended to change this
value because the backrest will not completely open to its vertical position which makes it dangerous for
the user who may risk being thrown forward.

“Actuator Setup” submenu displays all stander actuator settings for proper position angles to allow a
“comfortable” operation i.e. Soft start/stop. To adjust the stander actuator for a soft stop, use “Set point 1”. This
position is the first stop when the stander is deployed. This submenu also contains all the settings for actuator
movement speeds, acceleration/deceleration, starts and stops. The following table shows all the possible settings.

•Note 1 : Even though the standing function is adjustable, it is recommended not to change the value of
these two settings. This can affect the standing function’s performance and create errors while in motion.
Before modifying these settings, contact Amylior for approval.
•Note 2 : Even though the Control setting for the standing function’s axis is adjustable, it is recommended
not to change the setting to “proportional”. This can affect the standing function’s performance and
create errors while in motion. Before modifying this setting, contact Amylior for approval.
•Note 3 : For both axes reserved for memory positions (#11 & #12), Control must be set to non-
proportional for the Latched Actuators to work properly.
•Note 4 : The length of time from the minimum position to the maximum position (deployment) for each
actuator should be around the times shown in the following table.
2.1.5.2 Approximate length of time for actuator deployment
Recline: 26s
Seat elevaste: 23s
Right & Left legrests: 30s
Tilt: 22s
Center mount legrest: 25s
Stander (from the minimum position to the Soft Stop
“comfortable” position): 47s
Note that the default values were established for the chair’s optimal comfort and performance. It is
recommended to be very careful and vigilent before modifying any settings.
3E-bx special boot-up modes and position reset.
WARNING!
Never use special boot-up modes if the user is in the chair. This can cause serious injury to the user. When these
modes are in use, actuator movement limits are temporarily disabled and can create major mechanical conflicts.
These modes should only be used for troubleshooting different problems with the chair. Handle with care as there is
also a risk of damaging some of the chair’s mechanisms or components. Judgement and vigilance are key while using
these special boot-up modes. To exit the mode once it is no longer needed, turn the chair off and turn it back on.

11
3.1 Overview of both special boot-up modes
There are two special boot-up modes on the e-bx. These modes are very useful tools for technicians to determine
the cause or sources of power option failure; to boot-up actuators that may have lost their positioning; or to
replace a defective actuator related to the e-bx. Each mode has its own distinctive features.
3.2 Activating special boot-up modes
When the button underneath the e-bx is held during system start-up, the green LED flashes with a delay of two
seconds. The number of flashes corresponds to the mode required. Release the button when the number of
flashes equals the mode required. Therefore, if the first mode is required, release the button at the first green LED
flash and if the Second mode is required, release at the second flash.
Tables in this section provide a summary of features for each mode.
3.3 First special boot-up mode
This mode was designed to help determine if an actuator is defective or if it stopped moving because of a problem
with the controller. This mode can also be used for an actuator position reset. In this mode, all movement
limitations will be disabled except for minimum and maximum limits for each actuators under the "General"
submenu (section 2.1.2.1.)

•Note 1: Resetting actuators using the first special boot-up mode
For custom limits: Note all settings beforehand. Replace them with values shown in the Default Settings
column of the General submenu table (Section 2.1.2.1) and then proceed to a position reset of actuator(s).
Restore the settings to their original values before returning the chair to the user.
•Note 2: Resetting stander actuators using the first special boot-up mode
For the standing function, the center mount legrest actuator minimum limit and that of the stander
actuators are not set to the minimum physical limit of these actuators. Since the value shown in the
Default Settings column of the General submenu table (Section 2.1.2.1) is not the minimum physical limit
of stander actuators, the values must be replaced as follows:
→
Once these values are set, procced with a position reset of the center mount legrest actuator or of the stander
actuators through the first special boot-up mode.
Important! Prior to modifying settings, take note of the original values. These values will be restored before
returning the chair to the user.
3.4 Second special boot-up mode
Once the Second special boot-up mode is accessed, a position reset of actuators can be done by moving the
targeted actuators from the minimum position to the maximum position using the keypad (SWKEYPAD). Retract all
actuators to neutral position before exiting this mode and return to normal mode by turning chair off and back on.
To execute a position reset, refer to the Features column in the table below.

•Allows a minimum and maximum position reset of
actuators.
•Works only with pushbutton keypad (SWKEYPAD).
•Only actuators connected to channels A to E can be
activated. If needed, connect channel F actuator to
channel E to move it in this mode. The left pushbutton
activates channel A, the second from the left activates
channel B and so on.
•All automatic functions such as stander actuator
management during deployment and memory position
recall are disabled. All actuators become independent.
•The chair goes into drive lock-out and can no longer
move.

13
•Note 1: The Second special boot-up mode
Only in this mode, can actuators connected to channels A to E on the e-bx be activated. As an example,
upper and lower buttons on the extreme left of the keypad (SWKEYPAD) control the actuator connected
to channel A. The second set of buttons from the left, control the actuator connected to channel B and so
on for the other actuators. If an actuator is connected to channel F as in the case of the right legrest
actuator or the right stander actuator, disconnect one of the cables not going through the position reset
(among channels A to E) and connect the channel F actuator cable to the newly freed channel. Once
position reset has been done, reconnect actuator cables in their original channels.
•Note 2: Actuator position reset using the Second special boot-up mode
In this mode, if one or both stander actuators need to go through a position reset, the center mount
legrest needs to be completely up so that it doesn’t collide with the base when stander actuators deploy.
To prevent the stander mechanism from twisting, both stander actuators must move at the same time
while pressing upper or lower buttons on the keypad (SWKEYPAD) that correspond to the stander
actuators. Move stander actuators to a full deployment (both upper buttons) followed by a complete
retraction (both lower buttons).
IMPORTANT!
When an actuator is replaced, it must go through a position reset using the Second special boot-up mode
because the new actuator’s positioning may have changed during installation. In the case where an entire
standing module is replaced, a position reset is not necessary because the actuator cannot be incorrectly set.
4Troubleshooting guide
4.1 All about error codes
Important! Before handling anything, take note of the error code, the power option, the keypad’s (SWKEYPAD)
pushbutton(s) and/or the memory position that generated the error. Error codes are prompted either on the
joystick’s screen, with the number of times the light underneath the e-bx flashes or in the program journal of the “R-
Net Programmer” application. This is useful for knowing what direction to take when solving the problem.
Error code reading on the joystick’s screen
There are basically two types of joysticks: joysticks with a color screen and joysticks with a LED display.
A joystick with a color screen will show a message such as “e-bx Module Error 9662” to indicate an error. The
number in the message is the error code. The meaning of error codes is described in the Error Codes table in section
4.1.4 below.

14
A joystick with a LED display will show a change in the lighting pattern to indicate an error. Depending on the error
generated, the lights will turn on, turn off or flash. The meaning of error codes is described in the Error Codes table
in section 4.1.4 below.
Error code reading by counting the number of times the indicator light underneath the e-bx flashes
If there is an error, the green indicator light underneath the e-bx can indicate certain error codes. The error is shown
with a two-second pause separating the very first flash and the second flash. During this pause, the light is off. When
the light starts flashing, count the number of times it flashes before the light turns off again for another two-second
pause. After this pause, the light will flash again the same amount of times until the next pause, and the cycle
repeats.

15
Error code reading using the program journal of the “R-Net Programmer” application
Connect the R-Net dongle to the computer’s USB port.
Remove the chair’s backrest cover.
Plug the R-Net dongle into the chair by removing one of the R-Net cables connected to the chair, for
example, one of the 2 cables connected to the e-bx and turn on the chair using the joystick.
Open the PGDT « R-Net Programmer » application and click on Read, the icon with the black arrow point
down.

16
Click on the Tools tab.
Click on Systems Logs menu
The following window will appear on the left. Click on the Log tab and select Read menu.

17
From Module Log Info directory, select e-bx. The list of error codes will appear starting with 4400.
The e-bx actual error codes are not shown on the Dealer version of the application. The file containing the
error codes must be sent to Amylior to be examined and analyzed. To save the journal of error codes, click
on the File tab and select Save to file.
Choose the location for the saved file, e.g. the desktop. Send the saved file as an attachment in an email to
Amylior: [e-mail]

Error codes table
The table below lists possible error codes, the reason for error occurrence, and ways to resolve them. The
following section (4.1.5.1) describes methods on “How to” and provides “additional information”.
NOTE: In the table below, checking or replacing a cable (actuator extension cable or R-Net cable) can be done
with a temporary cable not belonging to the chair. This makes it possible to verify whether the suspected faulty
cable is truly defective without wasting time in unnecessary disassembly.

the R-Net power module and the e-bx.
5. If both R-Net cable buses are properly connected and in good
condition, replace the e-bx controller.
6. Once the e-bx has been replaced and the problem is solved, make
sure that power positioning modules do not jam and that all
actuators work properly throughout their entire range of
movement.
7. If one of the actuators does not work or constantly stops its
movement, it is possible that this actuator, its cable, or its power
positioning module could be the cause for premature wear of the
e-bx. In this case, also replace the actuator, its cable or the power
positioning module components as required.

The actual voltage of
the 12-volt supply in
the e-bx’s internal
circuitry is too low.
1. Reset alarm by turning chair off and back on, making sure the
error does not reoccur.
2. If error reoccurs, unplug the keypad’s cable DB9 connector
(female) from the e-bx, then turn chair off and back on.
3. If error does not reoccur, verify the condition of the DB9
connectors on the e-bx and the keypad cable. There shouldn’t be
any trace of verdigris, any crooked or broken pins. Replace the
e-bx or the keypad’s pushbuttons as required.
4. If error does not reoccur after disconnecting the cable from the
keypad and the DB9 connector are in good condition, properly
reconnect the DB9 cable back onto the e-bx and see if the error
reoccurs. If it does, replace the keypad’s pushbuttons.
5. If error reoccurs after disconnecting pushbuttons from keypad,
unplug all actuator extension cables from the e-bx, then turn
chair off and back on.
6. If error does not reoccur, verify that actuator extension cables
and those of the e-bx are properly connected and replace
inconsistent or damaged parts if need be.
7. Using a multimeter, reconnect, one by one, actuator extension
cables into the e-bx until error pops up. Disconnect from the e-bx
the cable causing error, but keep it connected to its actuator.
With the ohmmeter, measure the resistance between both
center female terminals on the extension cable. The ohmmeter
reading should be between 3.5 kOhms and 35 kOhms.

8. If the reading is lower than 3.5 kOhms, disconnect the actuator
from its extension cable and take another reading. The reading
should show the infinity sign (OL). If the reading is lower than
infinity (OL), replace the extension cable.
9. If the resistance reading is infinity (OL) on the extension cable
only and the value is lower than 3.5 kOhms, replace the actuator.
10. If a multimeter is not available and nothing is inconsistent or
damaged, reconnect each actuator extension cables, one by one,
to the e-bx until an error pops up and verify which cable or which
actuator caused the error. Turn off chair, replace extension cable
and reconnect actuator causing error. Turn chair back on.
11. If error reoccurs, replace the actuator.
12. If after executing all these steps, the source of the error is still not
found, replace the e-bx.

Problem with the
output unit of the e-bx
1. Reset alarm by turning chair off and back on, making sure the
error does not reoccur.
2. Make all actuators move in each direction. If error reoccurs,
replace actuator and its extension cable responsible for
generating the error and then replace the e-bx.
